Abstract

Highly nonequilibrium radiation transitions from electronically excited states generated by collisions of atomic oxygen with reaction control system thruster plumes is modeled for different altitudes and vehicle velocity conditions. The flowfield results are obtained using a Navier-Stokes solver to calculate the flow inside the nozzle and the direct simulation Monte Carlo method (DSMC) is used to simulate the chemically reacting, 3-D plume-atmospheric interaction. The radiation rate is compared for two types of overlay methods and with direct simulation in DSMC. The distribution function for collisional relative velocities is explored and used to interpret the sensitivity of the radiation rate to freestream altitude, temperature, velocity, and to the radiation mechanism activation energy.
